Merge pull request from minrk/websocket...

Merge pull request from minrk/websocket Websocket fixes: 1. alert client on failed and lost web socket connections A long message is given if the connection fails within 1s, which assumes the connection did not succeed. Otherwise, it is a short 'connection closed unexpectedly'. This also means that clients are notified on server termination (for better or worse). 2. remove superfluous ws-hostname parameter from notebook This made the notebook server artificially and unnecessarily brittle against tunneling and explicit hostname resolution. Now, the ws_url is defined based on the Origin of the request for the url, so it always matches the http[s] url. This means that it will follow the same tunnel, and the hostname will be already resolved. Resolving the hostname twice makes no sense at all unless the websockets are going to a different server than the http requests. Implemented as a property, so it should still be easy to change for future cases where it might behave differently (e.g. websockets on a different host, or at a non-root url).
